Controlled Quantum Teleportation Through Noisy GHZ Channel
Chun Miao, Yang Ming, Zhuo‐Liang Cao · Communications in Theoretical Physics · 2010
In this paper, we propose two physical schemes for teleporting an unknown atomic state through noisy channel in cavity QED. The quantum channel is a noisy one — a mixed GHZ state, which is more realistic in quantum information processing. We solve analytically a master equation in the Lindblad form with (L2,z, L3,z, L4,z)-type of noise in cavity QED. A comparison between the two protocols are discussed.
